These serial numbers can be used only as a reference point.
An Exact date does not make a material difference to an assessment of a piano - a year or so out 120 years ago really is neither here more there.

The idea that 100% accuracy for all piano makers over a century ago is an interesting thought - but considering that all record keeping would be hand-written and kept in large ledger books, inaccuracies are likely. These records will be as reliable as the clerks whose job it was to keep them. The digital age of barcodes and scanned labels was still in the realm of science fiction. So we have to be content with our best guess numbers.
